Window casement gear box
This looks like an awning window operator. We carry a bunch of different styles, which you can see on this page.
If you cannot find a replacement on this page, then I will need more detailed photos and information of your part. Please remove it from the window in its entirety and show me a clear picture of the hole pattern and another of the link arm. I need to see both without obstruction, so it's very important that it's out of the window beforehand.
Thank you
I agree. Looking over these photos, our 39-025 appears to be our best option. If I were you, I'd just double and triple check your measurements to ensure that they match the dimensions we show for this product.
